TL;DR
This work tackles the challenge of detecting client resistance in text-based mental health counseling by introducing PsyFIRE, a theoretically grounded taxonomy of 13 fine-grained resistance behaviors alongside collaboration. Building on PsyFIRE, the authors construct the ClientResistance corpus (23,930 annotated utterances from real-world Mandarin counseling) and develop RECAP, a two-stage, explainable framework that detects resistance and its subtypes with contextual rationales. RECAP outperforms strong LLM baselines, achieving 91.25% F1 in binary resistance detection and 66.58% macro-F1 in fine-grained classification, with significant gains when rationale generation is included. Additional analyses on an independent counseling dataset and a proof-of-concept study with 62 counselors demonstrate the model's prevalence insights, its relationship with therapeutic alliance, and its potential to improve counselor interventions through model-based feedback. The work provides a foundation for scalable, interpretable analysis of resistance in text-based therapy, with implications for training and real-time guidance, while acknowledging limitations related to cross-cultural generalizability and ethical deployment.
Abstract
Recognizing and navigating client resistance is critical for effective mental health counseling, yet detecting such behaviors is particularly challenging in text-based interactions. Existing NLP approaches oversimplify resistance categories, ignore the sequential dynamics of therapeutic interventions, and offer limited interpretability. To address these limitations, we propose PsyFIRE, a theoretically grounded framework capturing 13 fine-grained resistance behaviors alongside collaborative interactions. Based on PsyFIRE, we construct the ClientResistance corpus with 23,930 annotated utterances from real-world Chinese text-based counseling, each supported by context-specific rationales. Leveraging this dataset, we develop RECAP, a two-stage framework that detects resistance and fine-grained resistance types with explanations. RECAP achieves 91.25% F1 for distinguishing collaboration and resistance and 66.58% macro-F1 for fine-grained resistance categories classification, outperforming leading prompt-based LLM baselines by over 20 points. Applied to a separate counseling dataset and a pilot study with 62 counselors, RECAP reveals the prevalence of resistance, its negative impact on therapeutic relationships and demonstrates its potential to improve counselors' understanding and intervention strategies.
